FLUSHING APPARATUS FOR WATERCLOSET CISTERNS.

SPECIFICATION formi-ng part Of LttrsV Patent No. 345,390, dated July 13, 1886.

Y HApplication tiled April 26, 1886.

To all whom it may concern:

Be it known that I, JORDAN L. MOTT, Jr., of the city and State of New York, have invented an lImprovement in Flushing Apparatus for Water-Gloset Gisterns, of which the following is a specification.

Before my invention variable chambers had been made use of, into which water passed for regulating the speed in closing the valve in water-closets and in water-closet cisterns. My present invention is for facilitating the adjustment and regulating the time occupied in closingthevalve, thus preventing the wasting of water,and regulating with accuracy the quantity of water consumed in flushing the closet.

In the drawings, Figure 1 is a vertical section of my improvement, and. Fig. 2 is a detached sectional view at the regulating-valve, and at right angles to Fig. 1.

A portion of theA cistern is represented at 2, and a portion of the flushing-pipe leading to the water-closet is shown at 3. The valveseat 4 and its tubular socket 5 are usually connected to the cistern by a screw-nut and to the flushing-pipe by a coupling. The valve Gris at the lower end of the overflow-pipe 7, and these are raised by a lever, 8, and pull, at the water-closet, as usual. Around the valveseat is the cylinder 10, slotted at 11, for the water to pass freely to the flushing-pipe, and at 12 there is a septum within the cylinder 10, hav\ ing a packing-gland, 13, around the tubular overflow-pipe 7, so that said pipe 7 is free to slideendwise through such packing-gland; but the latter renders the joint watertight, or nearly so, and there is a movable head, 15, at the upper end of the cylinder 10, with a central opening for the overfiow-pipe 7 to slide freely therein.

Around the overow-pipe7, and within the cylinder 10, is the piston 20, preferably provided with a packing of felt or other material, and this piston is permanently attached to 45 and moves with the overfiow-pipe 7, when the latter is raised or lowered.

Serial No. 200,147. (No modeL) Through the septum 12 is an opening containing a valve, 22, opening upwardly, and adjacent to the lower end of this valve is the camend 25 of the screw 26, and this screwT passes 5o through the cylinder 10, and is provided with a handle, 27. When the cistern is to be flushed, the lever 8 is acted upon to raise the overiiow-pipe and the valve, and at the same time the piston 2O is drawn upwardly within the 5 5 cylinder 10, .and water is drawn in at the valve 22, said valve lifting by the action of the water. When the lever 8 is dropped, the ovcrflow-pipe 7 and valve 6 descend; but they cannot movcrapidly,because the water contained 6o 'in the cylinder l() holds up the piston 20, and

the speed with which the valve closes is regulated by the escape-opening at the valve 22.

If suchV valve 22 is lifted considerably by the 22 the extent of flushing action can be regu- 7o lated,and`the quantity of water flowing to the watercloset accurately adjusted, and this can easily be done from time to time by simply moving the lever 27.

. lf claim as my invention- The combination, with the overiiow-pipc 7 and valve 6, of the cylinder 10, surround ing the valve, and Slotted for the passage of the water, the septum 12, and. packing 13, within the cylinder and around the overliowc pipe 7, the piston 20, attached to such over" flow-pipe, the valve22, applied atan opening in the septum 12, thecam 25, screw 26, and lever 27, for regulating the position of the valve 22 and determining the time consumed in closing 8 5 the valve 6, substantially as set forth.

Signed by me this 20th day of April, A. D. 1886.
